ControlNet issue: TypeError: argument of type 'ControlLora' is not iterable

Expected Behavior

Used ControlNet with a PonyXL model to create an image.

Actual Behavior

After one or two successful generations, and no changes to any settings, I get an error message from the KSampler. File "D:\StableDiffusion\Packages\ComfyUI\comfy\ldm\modules\diffusionmodules\openaimodel.py", line 357, in apply_control if control is not None and name in control and len(control[name]) > 0: TypeError: argument of type 'ControlLora' is not iterable

I've tried using different KSamplers and different Apply ControlNet nodes, but same result. The error first appeared using the core nodes. I've also tried with different ControlNet models, and still the same.

Restarting ComfyUI solves the issue for one or two generations, then it returns. Bypassing ControlNet removes any issue. Screenshot 2024-09-06 150045
